Reasons Why Cooling Towers Fail
17 June 2019Cooling
towers represent an incredibly elegant solution to an age-old problem. The tech
behind these temperature-managing constructs basically scales-up a natural
process. Based on nature’s own heat exchanger mechanism, the principles at work
inside the towers can be found everywhere. However, these evaporative systems
have evolved to encompass many additional features, many of which assure an
environmentally safe air stream. What then happens if a cooling tower fails?
Troubleshooting Temperature Fluctuations
The
following faults are troubling, but things could be worse, as we’ll highlight
in a later passage of text. A cooling tower fails because its evaporative
mechanism breaks down. The evaporative water flow begins to warm. As a knock-on
effect, the air flowing through the structure warms too. Odds are the heat
exchanger isn’t working properly. The air that initially cools the water is
obstructed or low-flowing. Adjust the intake blades to correct the flow rate.
Another problem here is the water level. Obstructed by a clogged filter or a
jammed actuator, the water level rises too high. Because of the rise, the
sprinkler temperature fluctuates. Filter jams and/or actuator seizures impact
water or air flows. When those flows change unexpectedly, the functions of the
heat exchanger are impinged, too. When troubleshooting cooling tower failures,
those that impact temperature management performance, flow rates, leaks,
blockages, and parts failures are viewed as everyday culprits.
All About the Health Endangering Hazards
At least a
repair engineer knows where to look when a performance hit strikes. Elsewhere,
suffering from a progressive failure, the equipment will keep on working, but
at what cost? Drift eliminators, which are designed to reduce aerosolized
losses, can fail. Misaligned or broken, the “drift” escapes as a wet
stream. Imagine that wet load combining with concealed tower scale or some
stubborn bacterial growth. With the damp conditions concealed inside the tower,
the air quality begins to affect the weakened immune system of a child or
elderly person. Those drift eliminators cannot fail. They must be maintained.
By the way, talking of “health conditions,” we’re not limiting that
term to people.
Remember, cooling towers are used to regulate the functions of all kinds of
structures. In occupied places, they do cool people; that statement is true
enough. But, importantly, those structures also keep power stations and all
sorts of heat-producing industrial processes cool. If a failure occurs, a
controlled system, one that processes industrial-grade energies, could kick out
ungovernable amounts of thermal energy. That’s a dangerous situation. If a
motor fails, or a bearing breaks, or maybe a sprinkler system experiences a
blockage, building managers can’t work blindly. In this scenario, cooling
towers have real-time monitors, which act as system failure safeguards.
